MADRID, Aug 21 (Reuters) - Pope Benedict urged 1.5 million
young Catholics at a Sunday mass in an aerodrome near Madrid to
spread the gospel to others seeking better values than modern
society offers.
"We cannot encounter Christ and not want to make him know to
others. So do not keep Christ to yourselves! Share with others
the joy of your faith," he said in a sermon as part of the
activities of the Roman Catholic Church's World Youth Day.
The pope, closing a four-day trip to Spain which has been
marked by protests, told pilgrims from around 190 countries that
they have been given "the extraordinary task" of being
missionaries of Christ in other countries filled with young
people looking for better values.
"And, because their heart tells them that more authentic
values do exist, they do not let themselves be seduced by the
empty promises of a lifestyle which has no room for God."
Hundreds of thousands of young people, bearing flags from
their countries and wearing hats to protect themselves from the
sun, prayed, applauded and cheered during the service.
The pope read his sermon seated on a white throne under a
stylised golden tree, with Spain's King Juan Carlos and Queen
Sofia looking on. A choir and orchestra dressed in blue and
adorned with white lilies accompanied the mass.
PRAYER VIGIL
Benedict led a prayer vigil at the Cuatro Vientos aerodrome
on Saturday evening, but heavy rain prevented him from reading a
prepared speech in which he had made a veiled criticism of
Spain's legalisation of gay marriages and abortion.
An electric storm followed a day of sweltering heat in
Madrid, and wind during the night damaged tents, injuring seven
people, emergency services said.
Emergency services helped more than 1,500 young people
during Saturday's vigil, most with heat-related complaints.
But hundreds of thousands again packed the aerodrome on
Sunday to join the Mass, the highlight of the WYD jamboree.
"When you're at home you just think you're alone in your
faith, but when you pray with over a million people it just
changes things," said Katharina Eisen, 18, from Germany.
